This was recommended to me by my hairdresser when ask how i can get thicker hair. She explained to me how the products worse and how to properly use them.I must point out, although it is a little expensive, it is well worth it as the bottles themselves are quite large.This pack works by not causing you to grow extra strands of hair, but by increasing the density of each strand, which i can say has happened with my hair after using this only a month! I love the shampoo! The smell is quite minty, which i like. The good thing with this is, you really do not need a lot at all. I have long hair and only need to use about a 10p size in my hand because it lathers so well. I would say that the shampoo/cleanser is my favourite of the three products. As for the conditioner, it also smells minty but, as I have seen some people say, it doesn't leave my hair greasy whatsoever if anything i can now go longer before it goes oily. I massage into my scalp and leave this on for about three minutes as recommended (it is very important that you do put the conditioner on your scalp for the treatment to work) and it leaves my hair feeling soft and looking healthy. The only thing would say with this is to perhaps have another, cheaper conditioner that you can use on the length of your hair. I say this because, if you have long hair like me, you will need quite a lot of it to cover all your hair. The mouse, i have noticed people commenting on it leaving their hair stiff. I've found that by putting 1-2 pumps in to my hand and then using my fingertips to massage it into my scalp works best. I would say to use this on a night though as my hair does go a little hard at first, but by the morning it is totally fine. Overall, i would highly recommend this product to anyone who is wanting thicker, healthier and less oily hair.
